Java Android与spring文件上传丢失ServletRequestParameterException

我想将图像从android上传到spring控制器

我的问题是我无法上传文件，我在spring控制器中出错

我的android代码是：

 public String uploadImageToServer(final UserMO userMO,final Context context,final File profileImage) {
    final String jsonUserMo = gson.toJson(userMO);
    final StringBuilder contactLists = new StringBuilder();
    HttpClient client = new DefaultHttpClient();
    HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); // Timeout
    try {
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        FileBody profileFile = new FileBody(profileImage);
        builder.addPart("uploadImg", profileFile);
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("userMO", jsonUserMo));
        HttpPost post = new HttpPost(Constants.ROOTURL+"/media/uploadUserImage");
        String BOUNDARY= "--ringee--";
        post.setHeader("Accept", "application/json");
        post.setHeader("Content-Type", "multipart/form-data; boundary="+BOUNDARY);
        post.setEntity(builder.build());
        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        Log.i("Ringee",post.toString());
        HttpResponse response = client.execute(post);
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        contactLists.append(rd.readLine());
    } catch (Exception e) {
        e.printStackTrace();
    }
    return contactLists.toString();
}

错误：

org.springframework.web.multipart.MultipartRequest,javax.servlet.http.HttpServletRequest)]:
org.springframework.web.ind.MissingServletRequestParameterException:
Required MultipartFile parameter 'uploadImg' is not present

如何解决此问题请帮助我？

请更新代码：

     HttpClient client = new DefaultHttpClient();
     HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); // Timeout
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        builder.addPart("uploadImg", new FileBody(profileImage));
        builder.addPart("userMO",new StringBody(jsonUserMo, ContentType.TEXT_PLAIN));
        HttpPost post = new HttpPost(Constants.ROOTURL+"/media/uploadUserImage");
        post.setEntity(builder.build());
        HttpResponse response = client.execute(post)

     HttpClient client = new DefaultHttpClient();
     HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); // Timeout
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        builder.addPart("uploadImg", new FileBody(profileImage));
        builder.addPart("userMO",new StringBody(jsonUserMo, ContentType.TEXT_PLAIN));
        HttpPost post = new HttpPost(Constants.ROOTURL+"/media/uploadUserImage");
        post.setEntity(builder.build());
        HttpResponse response = client.execute(post)
